Abstract: The disclosed technology generally relates to integrated circuit devices with wear out monitoring capability. An integrated circuit device includes a wear-out monitor device configured to record an indication of wear-out of a core circuit separated from the wear-out monitor device, wherein the indication is associated with localized diffusion of a diffusant within the wear-out monitor device in response to a wear-out stress that causes the wear-out of the core circuit.

Abstract: A process for expanding tobacco is provided which employs carbon dioxide gas. Tobacco temperature and OV content are adjusted prior to contacting the tobacco with carbon dioxide gas. The disclosed process is suitable for impregnating and expanding tobacco having a high bulk density. In order to achieve a high bulk density, the tobacco may be compacted or compressed to achieve an increased and more uniform bulk density prior to its impregnation with carbon dioxide. The process may be carried out with a short cycle impregnation in an apparatus according to the invention. A thermodynamic path is followed during impregnation which allows a controlled amount of the carbon dioxide gas to condense on the tobacco. This liquid carbon dioxide evaporates during depressurization helping to cool the tobacco bed uniformly. After impregnation, the tobacco may be expanded immediately or kept at or below its post-vent temperature in a dry atmosphere for subsequent expansion.
